Touch for LED matrix panel?

by snaxter on Thu Jun 17, 2021 5:58 pm

I want to build a touch sensitive LED matrix panel. The rough idea is to tile 4 of the 64x64 LED panels (https://www.adafruit.com/product/3649) and add a touch interface. Is the best solution to add a resistive touch screen (https://www.adafruit.com/product/333) over the top of the panels? Has anyone seen other solutions, perhaps with a frame of IR emitter/detectors?

Thanks in advance for any thoughts you have...

Finger recognition with a camera? I saw an artist doing it like this with the same matrix panels at a local museum.
